| Abstract: | The paper used the microwave dispel-graphite stove atom absorption law to determine the trace amount of Lead and Cadmium in vegetables,optimized procedure of the microwave dispel and working condition of the graphite stove,discussed the substrate improvement medicinal preparation and acid-used choice of the microwave dispels.In this method the determination limit of Lead and Cadmium in vegetables is 0.002 mg/kg and(0.001 mg/kg) respectively and RSD is 0.1%~4.3% as well as returns-ratio of adding the sign is 98.0%~104%. |
